A series of pyrrole-thiazolidinone hybrids was designed, synthesized and evaluated for activities against ESKAP bacteria panel and mycobacterial pathogens. From the series, compound 9d showed prominent activity against S. aureus (MIC = 0.5 μg/mL) and compound 9k showed the most promising activity against M. tuberculosis H37Rv (MIC = 0.5 μg/mL). Potent derivatives were found to be non-toxic when tested against Vero cells. Compound 9d upon evaluation in vitro against several MRSA and VRSA strains produced activity comparable or better than standard drugs. In the anti-biofilm assay, 9d reduced S. aureus biofilm by >11% at 10x MIC. The dual inhibitory effect exhibited by pyrrole-thiazolidinone hybrids confirms their potential as new class of promising anti-infective agents.

设计、合成了一系列吡咯-噻唑烷酮杂化物，并评估其针对 ESKAP 细菌组和分枝杆菌病原体的活性。在该系列中，化合物9d显示出显着的抗金黄色葡萄球菌活性。金黄色葡萄球菌(MIC = 0.5 μg/mL) 和化合物9k显示出最有希望的抗金黄色葡萄球菌活性。结核病H37Rv（MIC = 0.5 μg/mL）。当针对 Vero 细胞进行测试时，发现有效的衍生物是无毒的。化合物9d在针对几种MRSA和VRSA菌株的体外评估中产生了与标准药物相当或更好的活性。在抗生物膜测定中， 9d减少了S。在 10 倍 MIC 时，金黄色葡萄球菌生物膜增加 >11%。吡咯-噻唑烷酮杂化物表现出的双重抑制作用证实了它们作为新型有前途的抗感染剂的潜力。
